Description

Technical Field

[0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a mobile operating platform. Background Art

[0002] The building flower racks are erected between adjacent buildings. In addition to improving the aesthetics of the building complex, large tempered glass will be installed on the top of the flower racks to form a rainproof corridor.

[0003] The main structure of a concrete planter consists of a foundation beam buried in the ground, a load-bearing beam connected to it, and a frame beam connected to the top of the beam. The foundation beam is cast separately, while the load-bearing beam and frame beam are cast together. For large cast-in-place structures, the concrete planter is typically level with the middle height of the buildings on either side to ensure effective connection and avoid an abrupt design shift.

[0004] After the concrete trellis is initially cast, the load-bearing and frame beams require surface treatment. Surface knots are removed and waterproof coating is applied. For aesthetic reasons, the concrete trellis is sprayed with a paint finish in various colors. The top and sides of the frame beams can be worked on in real time by workers. However, due to the height of the concrete trellis, the bottom and load-bearing beams require a mobile, liftable platform.

[0005] The main body of the lifting mobile operating platform consists of a fixed crossarm secured to the frame beam and a lifting platform equipped with an electric hoist. The fixed crossarm is fixed to one side of the frame beam using a multi-directional fixing structure. The lifting platform consists of a base frame and guardrails fixed to the edge of the base frame. The electric hoist is installed on both sides of the base frame, and the wire rope is fixed to the fixed crossarm. Construction workers stand on the base frame between the guardrails and operate the electric hoist to move the lifting platform up and down. To work on the bottom of the frame beam at a different location, the lifting platform is lowered to the ground, the multi-directional fixing structure is loosened, and the fixed crossarm is moved. Once the location is suitable, the lifting platform is moved to a prefabricated matching ground position and the multi-directional fixing structure is reinstalled. Workers can then perform surface work on the bottom of the frame beam at different locations. When the lifting platform is located next to a load-bearing beam, surface work can also be performed on the side of the load-bearing beam.

[0006] However, when this type of lifting mobile operating platform is actually put into construction auxiliary work, the main body of the construction platform is supported by traction ropes. During the construction on the surface of the load-bearing beam, the construction platform shakes due to the reaction force, which poses a certain safety hazard. In addition, when changing the construction position, the construction platform needs to be lowered to the ground, and the multi-directional fixed structure needs to be manually disassembled. When moving the position, in addition to manually lifting the fixed crossbeam, the lifting platform also needs to be manually lifted, and the whole operation is not very convenient. Therefore, it is necessary to provide a mobile operating platform that is more stable when implementing the construction on the bottom surface of the frame beam and the bottom surface of the load-bearing beam, and can more flexibly change the construction position.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The mobile operating platform includes two pairs of platform ring plates 1 for being mounted on the load-bearing beam. The platform ring plate 1 is provided with a semicircular plate structure with a square opening in the center. A sleeve frame 2 is welded along the square opening on each pair of platform ring plates 1. An opening and closing driving mechanism is provided at the rear of each pair of sleeve frames 2. The opening and closing driving mechanism is used to drive the opening and closing of each pair of sleeve frames 2. A limited fixing mechanism is also provided on the sleeve frame 2. The limited fixing mechanism is used to secure the platform ring plate 1 and the sleeve frame 2 on the load-bearing beam.

[0032] A side cover 16 is provided on one side of the platform ring plate 1 for sliding sleeves. A sliding plate 18 is welded on one side of the side cover 16, and a cantilever plate 19 is provided on the sliding plate 18 for sliding sleeves. A rotation mechanism is provided on the side cover 16 for driving the sliding plate 18 and the cantilever plate 19 to rotate along the outer edge of the platform ring plate 1. A telescopic driving mechanism is provided at the bottom of the sliding plate 18 and the cantilever plate 19 for driving the sliding plate 18 to extend and retract into the cantilever plate 19.

[0033] Among them, a movable traction mechanism is fixedly provided at the upper position of the cantilever plate 19, and the movable traction mechanism is used to move and lift the cantilever plate 19 and the platform ring plate 1 along the top frame beam.

[0034] See Figure 2 、 Figure 3 and Figure 5The opening and closing drive mechanism includes a first hydraulic cylinder 3 bolted to the rear part of the sleeve frame 2. The first hydraulic cylinder 3 is connected to the inlet and outlet liquid ends on one side of the reversing valve by a pressure oil pipeline, and the inlet and outlet liquid ends on the other side of the reversing valve are connected to the inlet and outlet liquid ends of the external hydraulic pump through a pressure oil pipeline. The push rod of the first hydraulic cylinder 3 is extended and retracted by controlling the reversing valve, wherein the push rod of the first hydraulic cylinder 3 is bolted to the outermost sleeve frame 2, and the bottom of the first hydraulic cylinder 3 is bolted to the innermost sleeve frame 2. Each sleeve frame 2 is vertically and evenly welded with a support tube 4, and a slide rod 5 is slidably inserted in the support tube 4 on each pair of sleeve frames 2. The slide rod 5 is a T-bar structure. The slide rod 5 is bolted to a baffle 6, and the baffle 6 is located between the sleeve frames 2.

[0035] The extension and retraction of the top rod of the first hydraulic cylinder 3 can drive each pair of platform ring plates 1 and sleeve frames 2 to be opened or closed, and the cooperation between the support tube 4 and the slide rod 5 makes the opening and closing of the sleeve frame 2 more stable, and the setting of the baffle 6 can prevent the load-bearing beam from directly pressing on the first hydraulic cylinder 3.

[0036] See Figure 2 、 Figure 3 and Figure 5 The limiting mechanism includes a second hydraulic cylinder 7 bolted to the sleeve frame 2, the push rod of the second hydraulic cylinder 7 passes through the sleeve frame 2 and is flange-connected to the pressure plate 8, and a contact plate 10 is bolted to the pressure plate 8. The contact plate 10 is vertically and evenly provided with anti-slip convex strips. A pressure sensor 9 is installed between the push rod of the second hydraulic cylinder 7 and the pressure plate 8. A side plate 11 is integrally provided at the front of the sleeve frame 2, and a third hydraulic cylinder 12 is bolted to the side plate 11. The push rod of the third hydraulic cylinder 12 passes through the side plate 11 and is bolted to the pressure plate 2 13.

[0037] The top rod of the second hydraulic cylinder 7 extends out, driving the pressure plate 1 8 to press the two sides of the load-bearing beam, and the top rod of the third hydraulic cylinder 12 extends out, driving the pressure plate 2 13 to press the front of the load-bearing beam, so that the platform ring plate 1 and the sleeve frame 2 are stably supported on the load-bearing beam. In addition, the two second hydraulic cylinders 7 and the two third hydraulic cylinders 12 on each pair of sleeve frames 2 are respectively connected to the branch inlet and outlet ends of the diverter and collector valve 1 through a pressure oil pipeline, and the main inlet and outlet ends of the diverter and collector valve 1 are connected to the inlet and outlet ends of one side of the electromagnetic reversing valve through a pressure oil pipeline, and the inlet and outlet ends of the other side of the electromagnetic reversing valve are connected to the external The hydraulic pump is provided with liquid inlet and outlet ends, and the control access end of the electromagnetic reversing valve is connected to the control input end of the PLC controller through a cable. In addition, the pressure sensor 9 is connected to the PLC controller signal through the transmitter connector, and the critical maximum pressure value in the PLC controller can be set. The critical maximum pressure value satisfies: after the pressure plate 8 is pressed tightly on both sides of the load-bearing beam, after a 1000KG weight is placed on the platform ring plate 1, the platform ring plate 1 and the sleeve frame 2 will not slide down, and it is set that when the uploaded pressure value reaches the critical maximum pressure value, the electromagnetic reversing valve is controlled to stop supplying oil to the second hydraulic cylinder 7.

[0038] See Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , columns 14 are welded on both sides of the fitting of the platform ring plate 1, and the height of the columns 14 is 1 meter. When the platform ring plate 1 is fitted, the columns 14 fit together, and retaining rings 15 are welded vertically and evenly between the columns 14. The distance between vertically adjacent retaining rings 15 is 30 cm.

[0039] When a pair of platform ring plates 1 are fitted together, the inner and outer retaining rings 15 form a human-defense barrier surrounding the outside of the load-bearing beam, thereby making it safer when performing surface construction on the outside of the load-bearing beam.

[0040] See Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The driving mechanism includes an annular groove 17 provided on the upper and lower parts of the platform ring plate 1. When a pair of platform ring plates 1 are fitted together, the annular groove structure formed by the annular groove 17 is provided. The upper and lower parts of the side cover 16 are integrally provided with an annular convexity. The annular convexity is an arc-shaped convex structure. The annular convexity is slidably inserted into the annular groove 17. Therefore, through the sliding cooperation between the annular convexity and the annular groove 17, the side cover 16 can rotate around the outer edge of the platform ring plate 1 more stably. A gear ring 291 is integrally provided in the middle of the platform ring plate 1. The gear ring 291 on each platform ring plate 1 is a semicircular gear ring. The top bolts of the cover 16 are fixed with a motor 28, which is a magnetic brake reduction motor. The power input end of the motor 28 is connected to the control input end of the forward and reverse controller through a cable, and the power input end of the forward and reverse controller is connected to the external power supply through a cable. The rotor shaft of the motor 28 passes through the side cover 16 and is connected to the center position of the gear 29 with an interference key. The bottom center position of the gear 29 is connected to the rotating shaft with an interference key. The inner bottom of the side cover 16 is provided with a ring groove, and the bearing is inserted into the ring groove with interference. The rotating shaft is inserted into the inner ring of the bearing with interference, and the gear 29 engages with the gear ring 291.

[0041] The motor 28 is controlled by the forward and reverse controller to drive the gear 29 to rotate. Since the gear 29 is meshed with the gear ring 291, it drives the cantilever plate 19 to rotate around the outer edge of the platform ring plate 1. It can also drive the platform ring plate 1 to rotate at the end of the cantilever plate 19 to change the opening direction of each pair of platform ring plates 1.

[0042] Among them, before the cantilever plate 19 rotates reversely with the outer edge of the platform ring plate 1 on the left, the pair of sleeve frames 2 and platform ring plate 1 on the right can be fully opened under the drive of the opening and closing drive mechanism, and the left driving mechanism can be controlled to drive the cantilever plate 19 to rotate reversely. When the pair of sleeve frames 2 and platform ring plate 1 on the right are completely separated from the right load-bearing beam, the pair of sleeve frames 2 and platform ring plate 1 on the right can be reclosed under the drive of the opening and closing drive mechanism, and the right driving mechanism can be controlled to drive the right platform ring plate 1 to rotate reversely, changing its opening direction to adapt to the insertion of the second load-bearing beam on the left.

[0043] See Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The sliding plate 18 is symmetrically welded with vertical poles 20 in the front and back directions. A retaining tube 21 is vertically and evenly welded on the vertical pole 20 on the left side. A bar 22 is slidably inserted into each retaining tube 21 and the right end of the bar 22 is welded to the vertical pole 20 on the right side. The height of the vertical pole 20 is 1.7 meters, and the sides of the vertical pole 20 are also vertically and evenly welded with side retaining rods 27.

[0044] The cooperation between the retaining tube 21 and the bar 22 can ensure that when the sliding plate 18 is extended and retracted in the platform plate 19, the cooperation length of the retaining tube 21 and the bar 22 is extended accordingly, thereby providing safety for the construction workers on the platform plate 19; and the minimum distance between the side retaining bar 27 and the retaining ring 15 is 3 cm. In this case, it is safer for workers to climb from the platform ring plate 1 to the sliding plate 18 or from the sliding plate 18 to the platform ring plate 1;

[0045] For greater safety, the worker can wear a high-altitude safety belt and hang the high-altitude safety belt rope ring on the retaining tube 21, and then perform a climbing action between the platform ring plate 1 and the sliding plate 18.

[0046] See Figure 1 、 Figure 4 The telescopic drive mechanism includes a first connecting block 30 welded to the bottom of the side cover 16, a second connecting block 31 is welded to the middle side of the bottom of the platform plate 19, and the bottom bolt of the fourth hydraulic cylinder 32 is fixed to the second connecting block 31. The fourth hydraulic cylinder 32 uses a pressure oil pipeline to connect the inlet and outlet ends of one side of the reversing valve one, and the inlet and outlet ends of the other side of the reversing valve one are connected to the inlet and outlet ends of the external hydraulic pump through a pressure oil pipeline. By controlling the reversing valve one, the extension and retraction of the push rod of the fourth hydraulic cylinder 32 is realized, and the push rod of the fourth hydraulic cylinder 32 is bolted to the first connecting block 30.

[0047] During the extension and retraction of the top rod of the fourth hydraulic cylinder 32, the sliding plate 18 is driven to extend and retract in the cantilever plate 19, thereby changing the matching length of the sliding plate 18 and the cantilever plate 19, which can be adapted to be installed between load-bearing beams with different spacings; in addition, when the opening and closing drive mechanism drives the outer platform ring plate 1 to move outward, the inner platform ring plate 1 can be driven to move inward by the telescopic drive mechanism, so that the inner platform ring plate 1 and the sleeve frame 2 can be separated from the load-bearing beam.

[0048] See Figure 1 and Figure 6The movable traction mechanism includes two support plates 33 installed on the top frame beam, and the four sides of the bottom of the support plate 33 are welded with side connecting blocks 34, and the side connecting blocks 34 are bolted to the fifth hydraulic cylinder 35. The top rod of the fifth hydraulic cylinder 35 passes through the side connecting blocks 34 and is bolted to the pressure plate three 36. The four fifth hydraulic cylinders 35 on each support plate 33 use a pressure oil pipeline to connect the branch inlet and outlet ends of the diverter and collector valve one, and the total inlet and outlet ends of the diverter and collector valve one are connected to the inlet and outlet ends of one side of the electromagnetic reversing valve two through a pressure oil pipeline, and the inlet and outlet ends of the other side of the electromagnetic reversing valve two are connected to the inlet and outlet ends of the external hydraulic pump through a pressure oil pipeline, and the control access end of the electromagnetic reversing valve two is connected to the control output end of the PLC controller through a cable. Therefore, the electromagnetic reversing valve two is controlled by the PLC controller to control the top rod of the fifth hydraulic cylinder 35 to extend or retract, thereby realizing that the pressure plate three 36 presses or releases the frame beam, and the fifth hydraulic cylinder 35 drives the pressure plate 36 to press against the frame beam, so that the mobile traction mechanism can stably lift and pull the platform plate 19; the top of the support plate 33 is bolted with a winch 37, the rotor shaft of the winch 37 is flange-connected with a rope pulley 38, and the rope pulley 38 is installed with a safety hook rope 25. The four sides of the platform plate 19 are provided with locking mechanisms and are connected to the safety hook rope 25 through the locking mechanisms. The sixth hydraulic cylinder 39 is bolted between adjacent support plates 33. The bottom bolts of the sixth hydraulic cylinder 39 are fixed to the support plate 33 on the left. The oil inlet and outlet ends of the sixth hydraulic cylinder 39 are connected to the oil inlet and outlet ends on one side of the reversing valve 2 through a pressure oil pipe, and the oil inlet and outlet ends on the other side of the reversing valve 2 are connected to the oil inlet and outlet ends of the hydraulic pump through a pressure oil pipe. The top rod bolts of the sixth hydraulic cylinder 39 are fixed to the support plate 33 on the right. A support pipe 40 is welded to the support plate 33 on the left, and a support column 41 is welded to the support plate 33 on the right, and the support column 41 is slidably inserted into the support pipe 40.

[0049] Therefore, by controlling the extension of the top rod of the fifth hydraulic cylinder 35, the pressure plate 36 is pressed against both sides of the frame beam, and by controlling the operation of the winch 37, the rope reel 38 is driven to retract and release the safety hook rope 25, thereby driving the platform plate 19 and the platform ring plate 1 to move up and down; and when the top rod of the fifth hydraulic cylinder 35 on the left support plate 33 is retracted, the top rod of the fifth hydraulic cylinder 35 on the right support plate 33 remains extended. At this time, the top rod of the sixth hydraulic cylinder 39 can be controlled to extend to drive the left support plate 33 to move to the left, and wait for the top rod of the sixth hydraulic cylinder 39 to be released. When the rod is extended to its longest state, the top rod of the fifth hydraulic cylinder 35 on the left support plate 33 is controlled to extend, the top rod of the fifth hydraulic cylinder 35 on the right support plate 33 is controlled to retract, and then the top rod of the sixth hydraulic cylinder 39 is controlled to retract, so that the right support plate 33 moves to the left, and then the top rod of the fifth hydraulic cylinder 35 on the right support plate 33 is controlled to extend, and the top rod of the fifth hydraulic cylinder 35 on the left support plate 33 is controlled to retract. This operation step is repeated, so that the mobile traction mechanism can be moved horizontally to various positions on the frame beam to perform lifting and pulling of the cantilever plate 19.

[0050] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The locking mechanism includes side blocks 23 integrally arranged on the four sides of the cantilever plate 19, and a hanging ring 24 is slidably inserted in each side block 23, and the safety hook of the safety hook rope 25 is hung on the hanging ring 24. A connecting pin 26 is inserted in the side block 23, and the connecting pin 26 passes through the through hole provided at the lower end of the hanging ring 24 and is screwed into the side block 23, so that the hanging ring 24 can be stably installed on the side block 23. In actual use, the safety hook of the safety hook rope 25 can not only be hung on the hanging ring 24, but also be removed from the hanging ring 24; especially when the cantilever plate 19 is rotated along the platform ring plate 1 on one side or the traction mechanism is moved horizontally along the frame beam, the hanging ring 24 can be removed from the safety hook of the safety hook rope 25, thereby not affecting the implementation of the above-mentioned actions.

[0051] In addition, the hydraulic pump is divided into two, one is placed on the platform plate 19 between the retaining pipe 21 and the bar 22 to supply power to the hydraulic cylinder in the lower platform; the other has its chassis tied to the support pipe 40 and the cylinder body of the sixth hydraulic cylinder 39 through wire to supply power to the hydraulic cylinder in the upper mobile traction mechanism.

[0052] The working principle of this embodiment is as follows:

[0053] Opening and closing drive mechanism and limiting mechanism: The opening and closing drive mechanism drives each set of platform ring plates 1 to fit together, and the inner and outer retaining rings 15 form a human defense barrier around the outside of the load-bearing beam, so that workers can stand on the fitted platform ring plates 1 to carry out construction on the surface of the load-bearing beam, and can also stand on the cantilever plate 19 to carry out surface construction on the bottom of the frame beam. In addition, the compression support of the limiting mechanism on the load-bearing beam makes construction on the platform ring plates 1 and the cantilever plate 19 more stable.

[0054] The opening and closing driving mechanism, the rotation driving mechanism, the telescopic driving mechanism and the limiting mechanism: first, the safety hook on the safety hook rope 25 is removed from the hanging ring 24, and the motor 28 drives the gear 29 to rotate. Since the gear 29 is meshed with the gear ring 291, the platform plate 19 is driven to rotate around the outer edge of the platform ring plate 1. At the same time, the platform ring plate 1 can be driven to rotate at the end of the platform plate 19 to change the opening direction of each pair of platform ring plates 1; during operation, before the platform plate 19 is reversely rotated with the outer edge of the left platform ring plate 1, the right pair of sleeve frames 2 and the platform ring plate 1 can be fully opened under the drive of the opening and closing driving mechanism. After that, the inner platform ring plate 1 is driven to move inward by the telescopic driving mechanism, so that the inner platform ring plate 1 and sleeve frame 2 are separated from the load-bearing beam, and the rotation driving mechanism on the left drives the platform plate 19 to reversely rotate; when the right pair of sleeve frames 2 and the platform ring plate 1 are completely separated from the right load-bearing beam, the right pair of sleeve frames 2 and the platform ring plate 1 are closed again under the drive of the opening and closing driving mechanism. , control the right driving rotation mechanism to drive the right platform ring plate 1 to rotate reversely, changing its opening direction to adapt to the insertion of the second load-bearing beam on the left; control the left driving rotation mechanism to drive the left platform ring plate 1 to continue to rotate reversely, during this process, the top rod of the fourth hydraulic cylinder 32 is extended and retracted, driving the sliding plate 18 to extend and retract in the cantilever plate 19, thereby changing the matching length of the sliding plate 18 and the cantilever plate 19, which can adapt to being erected between load-bearing beams with different spacings, until the right platform ring plate 1 moves to and stops near the left second load-bearing beam, control the opening and closing driving mechanism of the right platform ring plate 1 to make the pair of platform ring plates 1 reopen, and then control the left driving rotation mechanism to drive the left platform ring plate 1 to continue to rotate reversely, until the pair of platform ring plates 1 on the right are completely inserted into the second load-bearing beam on the left, and re-control the limiting mechanism on the platform ring plate 1 on the second load-bearing beam on the left to be pressed on the second load-bearing beam on the left, and follow this operation method until the lower platform is adjusted to the appropriate position;

[0055] Mobile traction mechanism: By controlling the extension of the top rod of the fifth hydraulic cylinder 35, the pressure plate 36 is pressed against both sides of the frame beam, and by controlling the operation of the winch 37, the rope reel 38 is driven to retract and release the safety hook rope 25, thereby driving the platform plate 19 and the platform ring plate 1 to move up and down; and when the top rod of the fifth hydraulic cylinder 35 on the left support plate 33 is retracted, the top rod of the fifth hydraulic cylinder 35 on the right support plate 33 remains extended. At this time, the top rod of the sixth hydraulic cylinder 39 can be controlled to extend to drive the left support plate 33 to move to the left, and wait for the sixth hydraulic cylinder 39 to be released. When the push rod is extended to its longest state, the push rod of the fifth hydraulic cylinder 35 on the left support plate 33 is controlled to be extended, the push rod of the fifth hydraulic cylinder 35 on the right support plate 33 is controlled to be retracted, and then the push rod of the sixth hydraulic cylinder 39 is controlled to be retracted, so that the right support plate 33 moves to the left, and then the push rod of the fifth hydraulic cylinder 35 on the right support plate 33 is controlled to be extended, and the push rod of the fifth hydraulic cylinder 35 on the left support plate 33 is controlled to be retracted. This operation step is repeated until the platform corresponding to the lower part of the mobile traction mechanism is hung on the safety hook of the safety hook rope 25 again on the hanging ring 24.

[0056] Therefore, the mobile operating platform is more suitable for performing surface construction on the four side surfaces of the load-bearing beam and the bottom of the frame beam while standing on it, and can change the construction position more flexibly when the construction position needs to be adjusted.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
